1 This invention relatesto newspaper printingpresses in which-one or more webs are fed into a folder at full speed with another sheared in athalf speed so as to vary the 45' number of pages in successive products, and t L I produces a paper of two parts havingdifi'erent number of pages. 1 t i The principal objects of this invention are to provide a simple and convenient means for 6w perforating and separating the half speed webinto paper lengths, and feeding them into a the folder with a complete length product of thefull speed webs to be cut ofi'afterwards to make a complete product; to feed them so as to lengthen the spaces between thehalf s eed sheets during. the feeding so that the. I'OIlt edge of the incomingsheet reaches a certain point a whole page lengthbehind the one in advance of it, and also to provide means for exactly registering the front edges of the severed half speed sheets at the points at which the full speed sheets or products will be severed in the folder.

Other objects and advantages of the invention will appear hereinafter.

the means associated therewith for engaging and holdingthewebs. p f As stated, this. invention relates to that type of newspaper press in which two or more webs of paper to are fed into a folder 10 at full speed andanintermediate web w is fed into the folder at half the speed of the other webs. I This is done for the purpose of varying the number of pages in successive products so that, for example, every other product may have'two extra pages takenfromthe u web w. The folder has a former as usual along it and'is provided Withcutting edges at intervals so as to produce perforations M or slits leaving the webs connected at spaces between them. These slits of course extend transversely of the web. They are formed so that, when the sheet ahead is pulled, the wehwill be separated along the That sheet can pass along into, the folder without interference [from the web to behind it,.which is held back by the fact that the'surface speed of the cylinders 11 and 12 is only half the speed of the other webs. This web'w passes in between the two webs to which are brought in over guide rollersandconducted through a horizontal space from these guide. rollers '16: to drag roll. 17. i This directs them into the former of the folder 10. The drag roll runsat a surface speed equalto that of the webs w. Above the drag roll is provided a shaft l8 on'which are mounted a series of levers "19each' one having'a stud 21 for-supporting alev'er 20. These levers are yield ,ingly and adjustably held by screw "rods 22 connected with the other armof each lever 19 and having a spring 23 for an obvious'pnrpose and an adjusting nut 24. These rods are comrectedto one end "of each lever 20..

- On'the other endof each lever is a roller 25-. This roller has :a portion of its circu nference 26 reduced so that it does not'come into co'ntact' with the drag roll during a part of the rotation. The rollers 25 are driven from the drag roll by gears 27.

The half speed web is fed in between the full speed webs in the horizontal path described. VJ hen the larger part of the roll 25 is in contact with the drag roll, these webs are nipped between these rolls. The half speed length is located between the two full speed webs and it will have to move at the samespeed as the two outer webs. The result of this is to tear the forward sheet from the web w and forward this'sheet at full speed. The two webs and one sheet go into the folder ready for the webs to be cut off at the end of thesheet and form a complete folded product. The horizontal path between the rolls 16 and 17 is of sufficient length to contain a considerable portion of the succeeding sheet of. the web w. This insures the proper entrance of the front edge of this succeeding sheet into its path, From the moment of severance, the space between the severed edges of-the half speed sheet be comes increasingly greater. When the front edge of the incoming sheet reaches the bite between the rolls 17 and 25, a space of a page length has been created.

It will be understood that the feed of the half speed web as described is of such a nature thata certain relationship has to be maintain ed between the drag roll, the surface of which runs at full speed, and the cutting couple, the surfaces of whichrun at half speed. They'are both driven from the same source. A shaft 30 is driven from the press by a chain and sprocket wheel 31 or in'any other desiredmanner. This shaft is directly geared to the spindle of the drag roll 17 by bevel gears 32 so that the drag roll is the other by gearing 35.

positively driven from the press at a speed governed by the speed of the press.

The shaft 30 is connected with a shaft 33 in alignment with it, which by bevel gears 34: drives the cutting couple. The cylinders of this couple are positively driven one from If the shafts 30 and 33 werein one piece there wouldbe no, or at leastno' convenient, way of registering the two sets of cylinders, that is, thedrag roll and the cutting couple, to produce exactly the right ratio. It is for this purpose that the shafts 30 and33 aremade separate. They are connected by a coupling 37 slidably keyed to the shaft 30 by keys 38; This coupling is connected with the shaft 33 by opposite angularly located slots 39 in the coupling fwh'ich' receive the opposite heads of a cross pin" 40. This cross pin is positivelysupported by the shaft 33 so that they must turn together about the axis of the shaft 33 relatively to the shaft 30. By shifting the coupling longitudinallythe. shaft 33 is turned angularly about its own axis.

A rod 12 with-an operating hand wheel 43 on the endof it is adjustably connected with ting couple as maybe desired. Thisisa screw adjustment'operated verysi mply for the purpose of registering the front edge of the severed half speed sheet with the point at which the full sheet will be severed in the folder It is the'cut in the half speed sheet that is regulated in this manner.

' It will be seen therefore that by this invention one or more ofthe webs w can'be fed into the folder at full speed. ,The web w is perforated across and fed in between he first-mentioned sheets at half speed.

This half speed web is'under the control of the cutting cylinders until separated from the next succeeding sheet. When it passes far enough along to reachthe bite between the rolls '17 and 25, it is suddenly speeded up to full speed thereby. This immediately pulls it apart atthe line of perforations. It then passes into the folder at full speed and the space between it and the forward end of the half speed sheet increases. The

angular position of the cutting cylinders is varied in the manner above described so that by the next time the forward end of the half speed sheet reaches the top of the drag 7 roll, a product containing an extra page or pages from the half speed sheet has been folded in the folder. Another product not containing any suchextra pages is being delivered to the folder, its'rear end being at the bite between the rolls 17 and 25. Thus every otherpr'o'duct may beprovided with two extra pages inthe form shown inthe drawings. Of course in this case one half speed web is fed between two' full speed webs and thehalfspeed web is only half the width of the full speed webs. .However, other combinations are possible according to the principles of this invention.
